When using the python debugger, most often I step ('s') through the
code base and I often Call the standard library modules, whichever are
imported in the scripts.
This is often not desirable as I know that errors are within my modules
and not in standard library.
Two things which a developer can do while using pdb is:

1. Be careful as not to 's' into stdlib but use next 'n'.
2. If accidentally stepped into, then use return 'r'.

Instead of doing this repeatedly, how about having method in the
debugger to skip certain modules ( like standard library modules,
certain package's modules etc)

This would save a lot of distraction in call and returns, and developers
can just go ahead with 's' and Enters.

Added a skip keyword argument to Bdb and Pdb class constructors to allow
skipping of modules based on a list of glob-style matches (see fnmatch),
as per the following example:

import pdb;Pdb(skip=['django.command*']).set_trace()
